====== Connect crop holes AB ======


===== Icon =====
{{:icon:crop_hole_ab_icon.png?50|}}

===== How it works =====

**Some tool functions are only available in expert mode**

This option lets you add a crop hole zone between two existing rows in order to merge plots.

The option is only available **when at least one map is loaded in the application**.

===== Application =====

When the option is started, a window appears allowing you to :
  * Select the project to be modified
  * Modify hole area  creation parameters
    * activate / deactivate hole area connection in automatic mode
    * Enable / disable creation of rounded crop hole zone
  * Manage existing holes areas 
    * You can activate/deactivate the deletion of points when deleting load-shedding zones.
    * You can click on an item in the hole area list to display it with a red filter, or delete it by clicking on the delete icon.


==== Automatic crop hole zone AB ====

The Automatic AB crop hole zone option is activated by enabling the **Auto AB crop hole zone connection** parameter and then clicking on the **LINK** button.

The option works in several stages:
  * Polygonal selection of point group A, i.e. the points at the end of the 1st plot. 
  * Polygonal selection of point group B, i.e. the points at the end of the 2nd plot.
  * Selection of 1st point A and 1st point B.

Once AB has been selected, the 1st hole area will be drawn between the row of point A and the row of point B, merging the two into a single row with a hole area running from A to B. Subsequent holes areas will be created by taking the nearest unselected points A and B for each hole area.

==== Manual AB hole area ====

The Automatic AB hole area option is activated by deactivating the **Auto AB crop hole zone connection** parameter and then clicking on the **LINK** button.

How it works: select the end of a row, then the end of a second row, and draw a hole area between the two ends.

==== Crop hole zone curves ====

The Automatic AB hole area option is triggered by activating the **Rounded crop hole zones** parameter, then clicking on the **LINK** button.
The option works either automatically or manually, depending on the **Auto AB crop hole zone connection** parameter.

If the rows are not perfectly aligned, the creation of curved crop hole zone prevents the robot from entering or leaving a hole area with a great an angle, by smoothing the curve of the trajectory.

==== Hole area deletion ====

Holes areas can be deleted from the **Management of load-shedding zones** section.
This can be done in two different ways, depending on the value of the **Delete points** parameter:
  * If the parameter is enabled, the row is cut at the load-shedding zone to form 2 rows.
  * If the parameter is deactivated, the row remains whole, but the relief zone property is removed.
